1. What is the Electric Garage Heater Calculator?

The Electric Garage Heater Calculator determines the appropriate heater size in BTUs per hour based on garage volume and desired temperature rise. Proper sizing ensures efficient heating and energy conservation.

2. How Does the Calculator Work?

The calculator uses the BTU calculation formula:

Where:

• \( Volume \) — Garage volume in cubic feet
• \( 0.133 \) — Standard heating factor for garages
• \( \Delta T \) — Desired temperature rise in degrees Fahrenheit

Explanation: The formula calculates the British Thermal Units per hour required to heat your garage space based on its volume and the temperature difference you want to achieve.

3. Importance of Proper Heater Sizing

Details: Correct heater sizing is crucial for energy efficiency, comfort, and equipment longevity. An undersized heater won't adequately heat the space, while an oversized one will cycle too frequently, wasting energy and reducing lifespan.

4. Using the Calculator

Tips: Measure your garage dimensions to calculate volume (length × width × height). Determine your desired temperature rise (difference between outside temperature and desired indoor temperature). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate garage volume?
A: Multiply length × width × height in feet. For example, a 20×20×10 garage has 4,000 ft³ volume.

Q2: What temperature rise should I use?
A: Typical rises are 20-40°F. Consider your local climate and desired comfort level.

Q3: Does insulation affect the calculation?
A: Yes, well-insulated garages may require less BTU. This calculation provides a baseline for standard construction.

Q4: Can I use this for other spaces?
A: While designed for garages, it can provide estimates for similar workshop or storage spaces.

Q5: What about electric heater wattage conversion?
A: 1 watt = 3.412 BTU/hour. Divide your BTU result by 3.412 to get approximate wattage requirements.
